Identify the characteristic of a mesh topology.
Mark scheme
- A Data can be sent by more than one route. (1)
- The only correct answer is A. The correct answer is that data can be sent by more than one route (accept equivalent wording, e.g. data can take alternative routes if a link fails).
- B is not correct because sharing a single backbone cable is a characteristic of a bus topology
- C is not correct because in a mesh devices connect directly to each other, not all to one central switch, which is a star topology
- D is not correct because terminators are used at the ends of a bus cable to absorb signals
Example answers and how they were marked
Full marks1/1
A Data can be sent by more than one route.
Why: Correct characteristic (1); mesh nodes provide alternative routes.
No marks0/1
D Signals are absorbed by terminators at each end.
Why: This is a characteristic of a bus topology, not a mesh topology; no mark.
No marks0/1
C Every device connects to a central switch.
Why: This is a star topology; a common misconception that a mesh also uses a central switch.
